Application led Bccember 2, 1914,. Serial No. 875,064.

To au whom t may concern Be it known that I, PHILIP F. Lnonr, a citizen of the United States, and resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Molds, of which the following is a full, clear, and exact specifcation.

This invention relates to improvements in molds, and more especially to those adapted for molding cement burial vaults, the outer side and end walls of which are of sheet metal detachably connected at their meeting ends by means of corner posts of curved or other form for ornamental purposes.

The object of this invention is a simple, effective and durable means, cheap of con struction for securing in their operative position the corner posts of a mold, the side and end walls of which are composed of sheet metal, and whereby-such corner posts may be easily and quickly locked thereto against accidental detachment, and likewise.

detached therefrom. l

With these ends in view, my invention finds embodiment in certain features of novelty in the construction, combination and arrangement of parts by which the said 0bjects and certain other objects are attained, all as hereinafter fully described with reference to the accompanying drawings, and more particularly pointed out in the claims.

In said drawings: Figure 1 is a bottom plan view of a mold in which my invention finds embodiment. Fig. 2 is a detail longitudinal section of the outer mold. Fig. 3 is a transverse section through both the inner and the outer mold, Figs. 4 and 5 are respectively enlarged elevations of the lock# ing cam. Fig. 6 is an enlarged detail section showing in perspective one of the corner pieces and reinforcing locking bars detached from each other, and Fig. 7 is a perspective view of one of the locking cams.

Similar characters of reference indicate the same parts in the several figures of the drawing.

6-6 indicates the opposing sides and 7 7 the opposing ends of the outer mold, and which for the purpose of lightness and cheapness are preferably composed of sheet metal, which side walls are reinforced at their opposite ends by upright bars 8-8 secured to the outer frame of the side walls by rivets 9, the end walls 7 7 being likewise reinforced by upright bars 10-10 at their opposite ends secured to the outer faces of the end walls by rivets 11-11. A

The bars 8 are longitudinally recessed on their inner face to form a seat 12. and shoulder 13, of which latter and the end of the adjacent side or end 6 or 7, as may be, constitute an abutment for a corner post 141, which -as shown in the drawing is rounded., but so far as my invention is concerned may be of any other cross-sectional form.

Integral with, or otherwise fixed to the corner member 14 is a lug 15, projecting through a slot 16 beyond the outer face of the bars 8, and perforated to form a bearing for a pivot 15a, projecting from an eccentric cam 17, provided with a handle 18,

whereby the sides and corner pieces of the mold are quickly attachable and detachable.

It will now be observed that the eccentric cams 17 are in their unlocked position when their handles are elevated as indicated by dotted lines, and are in their locking position when these handles are .depressed as shown in full lines.

Spaced apart from the outer member of the mold is the inner member of the mold consisting of opposing side walls 20, end walls 21, and bottom 22, formed of sheet metal and preferably reinforced by a number of longitudinally extending angle irons 23 secured thereto by any means suitable for the purpose, as by rivets or bolts (not shown) and one or more .transverse angle bars 24C, secured in any suitable manner to the bars reinforcing the inner mold longitudinally.

For strengthening the upper edge of a burial vault and providing a wider base support for the cover, not shown, usually employed in connection therewith, the sheet metal walls of the outer mold are bent outwardly as indicated at 25, as are also the upper ends of the corner posts 14E, as indicated at 26, and the reinforcing bars 8 as indicated at 27.

As the mold in which my invention finds embodiment is adapted and intended to be used for molding burial vaults and similar receptacles from liquid cement poured therein, the mold is turned upside down with reference to the article to be molded, and the outer mold projects above the closed bottom of the inner mold, and s open at both ends outer mold, followed by Vtroweling down the -upper surface thereof, which is the bottom surface vof the molded article, which latter `remains in the mold until set, and its walls are hard enough to sustain them when removed, from theV mold, and which may be quickly donerby loosenlng and `then re1nov- Ving the eccentrics fromV their pivots, followed Y by first removing the side and end walls, and subsequently theV corner posts of the outer mold. Y .Y

Among the advantages due to my invention may be mentioned that by securing a perforated lug to and projecting it from the corner piece through the sides of a mold,

' for Vsupporting thelocling cam, there is not o nly'provided a positive connection between Y such a cam and the corner piece, but the Y strongest' and most durableconstruction for locking a corner piece to the sides of a mold against accidental detachment, and also a construction by which a sectional mold may be assembled in its operation and taken apart fin' the quickest possible time by workmen moreV or less unskilled in mechanical devices.

My invention therefore extends to and includes a moldprovided withY detachable corner'sections.wherein pivoted locking cams are positively connected with. and supported from the corner piece, and whereby the opposing corner piece and sides of the mold are simultaneously moved toward each other on the locking devices toward a locking position.

Having described my invention, what I claim and desire to secure by Letters Patent is:

l. A mold comprising in combination side and end walls, a detachable corner section, locking cams, a pivotal support therefor projecting from the corner section through said side and end walls.

2. A mold comprising in combination reinforcedsheet metal side and end walls, a detachable corner section for the mold, a perforated lug iiXed yto the corner piece projecting through the reinforcement for said walls, and locking cams detachably pivoted in said lug. j

3. A mold comprising in combination op posing side and end walls, and separato corner pieces, reinforcing bars respectively at the opposite ends of said walls, provided with a recess upon -their inner face forming an abutment for the corner pieces, perforated lugs projecting from the cor-ner pieces through the reinforcing bars, and locking cams removably sleeved in said lugs, adapted to engage the reinforcing bar whereby the corner sections and the side walls of the mold 'are simultaneously moved toward each other, and detachably locked in their operative position.

In Witness whereof, I have hereunto set my hand and affixed my seal this 28th day of November, A. D. 1914.
